BUILDING IN PRE-HUNG UNITS

  • Securely fix pre-hung unit square and plumb into brick/ blockwork coursings. 4 fixing points per jamb are recommended using suitable frame anchors. This may depend on the house construction
  • Allow brick/blockwork to set around the frame before removing the bracings
  • The door may be removed by carefully tapping out the hinge pins. Keep these with the door
  • Doors should be coded to ensure proper matching on refitting
  • Fit lock where necessary into pre-cut position and secure. Fix levers in position. Fix lock keep/s into position where necessary
  • If required, ‘ease’ the door before painting

FIXING PRE-HUNG UNITS INTO EXISTING OPENINGS

  • Check that rough opening is square and plumb
  • Apply mastic to the floor slab and to the underside of the timber / plastic sill
  • Centre the unit in the rough opening and hold in place by placing shims between the wall and the jambs, making sure the unit is square and plumb
  • Remove the bracings to allow the door to operate
  • Fix the hinge jamb to the wall with fixings (Fischer Fix frame bolts or similar are recommended, depending on construction)
  • Secure top and bottom fixing first. Recheck that the frame is plumb and square and adjust the shims between the lock jamb and the wall if necessary. Starting at the bottom, fix the lock jamb to the wall through the rebate
  • After fixing at the bottom, check that the frame has not twisted by trying the door for contact with the compression weatherstrip
  • Adjust jamb position if required. Fix at remaining positions. Fit lock into pre-cut position and secure, fix levers into position, fix keeps into position

NOTE! Packing MUST be used between frame and wall around the fixing positions. This will avoid the frame becoming distorted.

Packing MUST also be placed behind the locking keeps between the frame and wall. Frame fixings should be made above and below the keeps. After fixing is completed the door should be closed against the weatherseal ensuring it makes FULL CONTACT, the keeps on MPL locks can be moved for full adjustment.

INSTALLING PVCu FRAMES

  • Door and frame must be fitted as a complete unit
  • The sill MUST be bedded on mastic

FULLY SUPPORTED and LEVEL

  • The hinge jamb should be fixed first. Using a large spirit level ensure that all jambs are square and plumb. The door should then be closed against the lock jamb ensuring that the door makes FULL CONTACT against the weatherseal. The jamb should then be fixed into position

THRESHOLD

  • The threshold strip must be fixed securely using at least 3 fixings. A continuous silicone seal should be applied to the underside of the threshold before fixing and also to the ends of the threshold where it meets the frame to ensure weather tightness
  • It is important that the door is fitted correctly (square and plumb) and the threshold seals form a good seal across the width of the door
  • In exposed locations it may be necessary to apply additional sealing around/ underneath hardware items and fixings such as handles and cylinders

APPLYING PAINT FINISH TO STEEL / GRP DOORS PRIMED DOORS AND FRAMES SHOULD BE PAINTED WITHIN 3 MONTHS OF DELIVERY

  • Wipe the door with a pre-paint wipe or similar to remove any possible contaminants from the door
  • The sheen of the primer coating must be removed by lightly rubbing with fine abrasive paper or scotch pad
  • Clean off all dust and dirt with water and allow to dry, ensuring the surface is clean before painting
  • Apply paint (undercoat and gloss) to door
  • The glazing frame must also be painted following the paint manufacturer’s instructions
  • Do not paint the frame weatherstrip
  • Make sure the door is completely dry before closing to avoid marking the face of the door with the weatherstrip

CLEANING THE DOOR AND IRONMONGERY

  • Metal polishes, abrasive cleaners, chemicals or cleaning solvents SHOULD NOT be used to clean Ironmongery on the door. (This could deteriorate the item and invalidate the warranty)
  • To prolong the life of the furniture and the paint finish of the door, regular dusting with a soft cloth or camel hair brush, supplemented by regular washing with warm soapy water, is recommended, especially in industrial areas or coastal locations
  • Lubricate door mechanisms with light oil about once a year. Avoid scratches from rings and keys

PRE-FINISHED STAINED DOORS

  • IG Doors guarantee the paint finish for 3 years, after this period stain/paint may need to be re-applied on a regular maintenance cycle by customers. Instruction procedures are available on request.

REPAIRING DENTS OR SCRATCHES

Accidental dents or scratches may be easily repaired as follows:

1.  Sand the damaged area making sure all the base primer is removed
2.  Apply a fibreglass plastic filler (similar to that used for car body repair) and follow the manufacturer’s instructions
3.  Rub down repaired area and re-paint with undercoat and gloss

GENERAL

Sills MUST be bedded on either mortar or mastic and FULLY SUPPORTED

We recommend doorsets and components are stored in a dry, covered area.
